Incomplete Gamma Function In MatLab®

Like gamma functions, incomplete gamma functions can also be calculated in Matlab® with the required inputs. The ‘gammainc()’ command is again used in the calculation of the gamma functions in Matlab®. 

You can find detailed information about the incomplete gamma functions in advanced mathematics from this link.

You can try the example codes below in your Matlab® software. 

How To Use The ‘gammainc()’ Function In MatLab®?

>> gammainc(2,3)

ans =



As you see above, the use of the ‘gammainc()’ command is very easy in Matlab® to calculate the incomplete gamma functions. You just need to type two variables inside the brackets of the ‘gammainc()’ command. Then hit the ‘Enter’ key to see the result.

According to this integral above, you are entering the two variables ‘a’ and ‘t’ respectively inside the brackets of the ‘gammainc()’ command in Matlab®. 

This is the general expression of the incomplete gamma function in Matlab®. 


So, the calculation of the incomplete gamma functions in Matlab® is very simple with the ‘gammainc()’ command.
